Hostapd 丢失

Mar*_*rcF 11 12.04 hostapd

我已经按照使用 ubuntu 12.04 的几个操作方法将 hostapd 配置为接入点。一切正常运行长达几个小时，然后在某些时候 hostapd 不再接受新连接。

hostapd 配置如下：

ssid=PNN
wpa_passphrase=somePassphrase
interface=wlan2
bridge=br0
auth_algs=3
channel=7
driver=nl80211
hw_mode=g
logger_stdout=-1
logger_stdout_level=2
max_num_sta=255
rsn_pairwise=CCMP
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP

使用输出

hostapd -dd /etc/hostapd/hostapd.conf

在正常情况下，新连接的拾取方式如下：

我已经尽可能多地阅读并尝试将 wlan2 的 txpower 从 16dbm 降低到 10dbm，因为稳定性问题，但问题仍然存在。

如果有人可以提供帮助，将不胜感激。

  1. 运行sudo iwconfig并关闭卡的“电源管理”。重新启动，看看现在是否正常。再次重新启动，看看现在是否正常。如果没有，我们必须将其添加到Startup Applications.

  2. 我的一个朋友也面临着同样的问题。默认的 Atheros 驱动程序应该受到指责。您的 TX 日志已满，导致身份验证失败。

    在“软件源”/“软件和更新”中，启用“更新”选项卡下的“向后移植”。

    然后更新系统。

    还： sudo apt-get install linux-backports-modules-cw-3.6-precise-generic

    重新启动并检查。

  3. 如果仍然失败，请检查此处：已解决：Ubuntu 12.04 Wifi 驱动程序

@TomKat 是对的，它无法进行身份验证握手的原因是因为您的 TX 日志已填满 255 个条目。之后，您重新启动进程，一段时间内一切都会恢复正常，然后重复相同的问题。降低发射功率会减慢故障间隔时间的原因是，您基本上限制了可能连接的范围，因此以“每小时”为基础，该范围内的人数较少。所以更少的连接=更长的故障间隔时间...或者我可能会再次陷入困境。
